Okay! New question :D

How do you guys do when painting the steel parts?

The frame will get painted up to the epoxy strip. That's easy! And rhe gantry is extrusion au naturale. But all the different parts of my Z axis are milled flat. If I paint before mounting rails or carriages I might get problems?
If I paint with everything attached and mask the rails of there may be ugly gaps if I have to move/adjust something?

What to do?
